MILK-WEIGHING MACHINE,

Patented oct. 24, 1911.

To all whom it may commi:

Be it known that we, GEORGE R.- MEnoNEr and ALFRED F. l/Vooo, citizens of the United States,- .residing in Philadelphia, Pennsyl- Vania, have invented certain Improvements in Milk-WVeighing Machines, of which the following is a specification.

This invention relates to mechanism particularly designed to record upon a tape or certain numbers or symbols, which shall designate the particular cow giving the milk weighed, as Well as the date upon which the weighing takes plzce.

Another object of the invention is to provide a recording weighing machine, which shall include, means for simultaneously marking upon the ribbon the impression of a portion of a scale depending upon the weight of the body under treatment, together with a pointer or index mark, and a number indicative or characteristic of the body whose weight is recorded.

It is also desired to provide a machine of the above noted character with improved inking and printing mechanism, as well as with novel means for intermittently feeding a recording, ribbon, and operating and adjusting the various parts.

These objects and other advantageous ends we secure as hereinafter set forth, reference being had to the accompanying drawings, in which 4 Figure 1, is a front elevation of our improved machine; Fig. 2, is aside elevation of the machine shown in Fig. 1; Fig. 3, is a plan; Fig. 4, is a vertical section on the line f li, Fig. 3; Fig. 5, is a vertical section on the line 5 5, Fig. 3; Fig. 6, is a vertical section on the line 6-6, Fig. 1, and Fig. 7, is a fragment of the paper, or other reco-rd receiving tape, showing a series of records thereon produced by the operation of our machine.

The frame of the device consists of a back plate A and a front plate A', both of a gen erally 'rectangular form and rigidly conlnected, so as to lie parallel with each other,

by meansof four bolts or spacing bars a preferably extending between their corners. The back late A may be connected by means of bo ts a to any suitable vertical supporting structure A2, and it will be noted that it has an upper extension a2 and a lower extension a3, the first of which is overhung and perforated for the passage of a threaded rod b carrying on its upper end an adjusting nut b. Said rod carries a yoke piece b2, to each end of which is connected the upper end of a spring b3. The lower ends of these springs are connected by a transverse bar b, from which depends a` rod b5 passing through an openlng in the outwardly projecting end of the plate extension a3 and carrying at its extremity a hook b6 for the attachment of any object to be weighed.

Extending between and journaled in the two plates A and A is a shaft or spindle c to which is fixed a pinion cmeshing with a vertically extending rack 127 whose lower end is connected to the transverse bar b4, in the present instance by means of the pin bs whereby the bar b5 is also attached. To this same shaft c there is also lixed a printing wheel c2 which is preferably placed immediately adjacent to the rear face of the front -plate A and is provided on the out/er or peripheral portions of its inner face with a series of scale divisions and indicating numbers` both preferably raised or in relief.

While in the present instance the scale with its numbers is integral with the body of the wheel which is preferably of brass,

any other known or yequivalent means of mounting type on this wheel may be employed without departing from our invention.

The front face of the wheel is visible through an opening a* in the front plate A', and is preferably marked with an arrow or other symbol, so placed as to be in line with a stationary pointer a5 mounted on said front plate, when the Zero of the scale is in a predetermined position. Said pointer extends into this opening a", through which the symbol or mark on the wheel is visible.

The shaft o with its wheel is preferably mounted to one side of the center of the frame and upon its other side is mounted a second and preferably similar wheel d2.

This wheel is carried on a short s indle d revolubly mounted in the frame an having a milled'head d projecting from the front of the plate A so as to be readily turned by hand. This second wheel lies in the plane of the wheel c2 and like it is rovided around the periphery of its inner ace with a series of raised figures of type, which inl this instance run from 1 to 50; the front face of this wheel being provided with similar figures, which are visible through an opening a in the plate A, as indicated in Fig. 1. This opening is provided with a stationary pointer a? designed to coperate with this latter set of figures, 4each of which is displaced around the periphery of the wheel through an angle of 45, relatively to the same figure in the other set.

It will be noted that the two wheels c2 and d2 extend near each other, and, as shown in Figs. 5 and 6, there is mounted on the front plate A, immediately adjacent to the front surfaces of the adjacent portions of these two wheels, an abutment formed by a circular plate or block e which is held in place by a bolt e and is provided on its rear face with an indicating symbol e2, having the form of an arrow, as shown in Fig. 5, and projecting so that its face lies in the plane which includes the type or printing vfaces of the number on the wheel d2 and of the numbers and scale on the wheel c2.

To the rear of the two= wheels and directly back of the block or plate e, we mount a striking platen f carried upon an arm. f which in turn is movably mounted upon a supporting bar f2 extending transversely of the frame. This bar is carried by brackets f3 fixed to the lower pair of bolts or spacing members a. This platen f is elongated in form and is preferably, though not necessarily, made of a material softer than that of the type on the wheels c2 and d2, it being faced in the present instance with hard rubber. As shown, there is at its lower part a raised portion f44 directly back of a short length of the scale on the wheel c2, and this raised portion extends also immediately back of the raised symbol e2 onl the block e and back of a section of the wheel d2 at least as wide as the space occupied by one of the,

numerals thereon. At the upper end of the platen is a second raised or projecting portion f5 directly back of an opening in the top portion of the plate A and above the two type wheels. Mounted on the front of said plate A is an angle bracket g to which is pivotally connected an arm g carrying at its upper end a series of typewheels g, g", g and g', and having also a projecting stud g2 in which is mounted an adjusting screw g8. These various type wheels are revoluble upon their supporting spindle g8 and have on their peripheral portions raised type, those on the wheel g being capable in the esent instance of bols M. and P. M.

The wheel g has raised type corresponding to any of a number of years, the wheel g is provided with type indicating the days of the month, andthe wheel g7 has type indicating the various months. The arm g on which these type wheels are carried, while normally resting upon a stop as shown in full lines, is capable of being turned on its pivot into a vertical position as indicated in dot-ted lines in Fig. 6, so that it projects through the opening in the upper portion of the plate A to a distance sufiicient to permit certain of its type to extend. into or preferably slightly beyond the plane of the type faces of the wheels c2 and d2.

From Fig. 4f, it will be seen that the arm f has an extended hub f held from moving longitudinally on its supporting rod j? by means of collars j" and f1, and is also provided, as shown best in Figs. 2 and 6, with a projecting arm f8. ln addition there is a projection f on the arm f which has pivoted to it a headed rod i1.. The collar flo has a rearwardly extending portion f through which is a hole for the passage of the rod il. and there are springs L and h2 placed respectively between this arm and the two heads of said rod 7L; the whole being so arranged that the arm f is normally held in the position shown in Fig. 6, and tends to return to such position when moved therefrom.

For the purpose of actuating the arm f in such manner as to cause the platen f thereof to move toward the type wheels, so as to always strike a sharp rebounding blow of the same force, we provide an operating trigger 7c, consisting of a curved upwardly extending arm pivoted on a pin lc carried by an angle bracket K fixed to the front plate A. Pivoted to a projecting portion of this arm is a dog k2 normally maintained in a definite position by means of a spring ,7c3 and capable of engaging the arm fs of the hub f, though for a part only ofthe downward stroke of the trigger k. During the first part of this stroke the said dog engages the arm f8 and turns the hub on its supporting bar, moving the platen f to the rear against the action of the spring L. Owing, however, to the circular path followed by the arm f8, it is shortly disengaged by the dog, after which the above mentioned spring causes the hub,l and with it the arm f', to turn quickly on the supporting bar,vwith the result that the platen would violently strike the type ofthe various wheels, as well as the symbol e, were it not for the fact that the recording and inking ribbons hereafter described are interposed.

The operating trigger is normally maintained in its upper or raised position by printing the symmeans of a s ring la* extending between it4 spring may be forced against the side oft e wheel so as to exercise various amounts of resistance to the movement of the same and so regulate at will the tension of the paper ribbon. I

pair of guide spindles Z, 'Z are mounted on the bracket K just at or slightly below 30 the lower edge of the plate A, so as to receive the paper ribbon between them, and a second set of similar parallel guide spindles Z, Z are likewise mounted on the same bracket-at or slightly above the upper edge of the plate A. Above these two last spindles and somewhat to the rear of them are mounted a pair of feed or nip rolls Z2 and Z3, the rst of which is iixed to a spindle Z* revolubly carried by the bracket K. The second nip roll Z3 is revolubly carried by a spindle Z5 which in turn is mountved upon an arm Z pivoted to the bracket K and normally pulled toward the nip roll Z2 by a spring Z7. The paper'ribbon thus extends from the reel 7c between the two guide spindles Z, then upwardly to the rear of the two type wheels c2 and d2, in front of the platen f, between the two guide spindles Z, and finally between the two nip rolls Z2 and Z3. Projecting parallel to each. other from the top and lower portions respectively of the bracket K, are two additional spindles m and m upon which are two reels m2 and m3 for the reception of the type inking ribbon. Loosely carried on the lower spindle fm, is a wheel m* operatively attached to a similar wheel m5 on the upper spindle m by means of a connecting rod m6,' the arrangement of parts being such that movement imparted to one wheel turns the other wheel in an opposite direction. A link m7 connects the upper of these wheels m5 and the operating trigger Z@ in such manner that when said trigger is depressed, said wheels are turned through the same arc but in opposite directions.

As shown in Figs. 1 and 6, there are mounted upon the two spindles m and m two ratchet wheels m8 and m9 respectively, the first being detachably connected to the wheel m2 by means of a pin m1", while thc second is similarly connected to the wheel m3 by means of a pin m11. Each of the wheels m2 and m3 has pivoted to it a pawl p normally held in engagement with one of 4the ratchet wheels m5 and m9 by means of a spring p. Each of the pawls 1s provided with a projecting pin p2 and there is slidably mounted on the bracket K a flat bar g having a slot for the reception of a guide pin g and formed with its ends bent over so as to be capable of engaging either of said pins p2. -There is on said bar an operating head g2 whereby it may be moved up or down at will and thereby caused to raise the upper pawl p of the reel m3 out of engagement wlth the teeth of the ratchet wheel m9, or on the other hand to lower the pawl p of the reel mZout of engagement with the teeth of its ratchet wheel m8. Each of the spindles'ml and m is threaded at its free end for the reception of a milled head nut m12, and each of these nuts confines between itself and one of the ribbon reels an armed spring m13 whereby the pressure exerted upon said reels may be varied at will so as to regulate the tension of the ink ribbon y. This latter ribbon, as will be seen from Fig. 2, extends from the lower reel m2 over one of the guide spindles Z, then upwardly parallel with the paper ribbon and between this and the type wheels, finally passing over one of the upper guide spindles Z to the upper ribbon reel m3.

Pivoted to the upper wheel m5 is a pawl Z8 capable of engagement with a ratchet wheel Z9 fixed to the nip roll Z2; there being a spring Z1 extending between the -pawl and a portion of the bracket K whereby the former is normally maintained in `engagement with the teeth of said ratchet wheel.

Under operating conditions, with the paper and ink ribbons arranged as shown in the drawings, the adjusting nut b is manipulated until the zero symbol on the wheel c2 is directly opposite the arrow a5 as shown in the opening a4. This adjustment is made by reason of the fact that the raising o-r lowering of the screw Z: by means of this nut correspondingly raises or lowers the yoke b2, the springs b3v and the transverse bar b4,

which in turn moves up or down the rack 67 v and turns the pinion c with the shaft c so to the desiredposition, with the zero of its scale immediately adjacent to the symbol e2. The head aZ is then turned and with it the type wheel d2 so as to bring opposite the pointer a7 the particular number by which the cow, whose milk is to be weighed, is designated. The type numerals on the rear face of this wheel are so arranged that under these conditions the same numeral is brought immediately adjacent to the fixed symbol lc2 on the block e, as shown in Fig. 3. The arm g is then moved into the position shown in dotted lines in Fig. 6, the various type wheels carried thereby having been previously moved to definite positions, as indicated by a pointer g" carried by the arm ribbon upon the paper ribbon, which with it is interposed between said type wheels and said platen. The record thus made has the appearance indicated at :1:5 in Fig. 7, and it is to be noted that the blow struck by the platen upon the type wheels causes the arm g to turn on its pivot and fall to its normal position shown in Figsl, 2 and 6.

It will be noted that the downward movement of the trigger 7c causes a turning of the two Wheels m4 and m5 and a corresponding partial revolution of that one of the ink ribbon reels m2 or m3 depending upon which one of the pawls p has been placed in engagement with its ratchet wheel. As a consequence, the ink ribbon g/ is fed forward for a delinitey distance. The movement of the Wheel m gives a corresponding movement to the pawl ZS, so that the nip roll Z2 is turned and the paper ribbon is fed forward a de-linite distance. The pail containing the milk to be weighed is now hung from the hook be, though if desired, the empty pail may have been previously hung on the hook and the zero adjustment of the type wheel 02 made in order that the weights recorded may be net weights of the milk. As a result of this weight applied to the hook, the type Wheel 02 is turned through an angle proportional to and depending upon the weight of the milk, and the type numerals and scale on said wheel are so arranged that when the various parts are in equilibrium the numeral or scale divisions indicating this weight is directly opposite the indicating arrow e2. A second depression of the trigger lc again draws back and releases the arm f, so that the platen f5 makes another sharp forward movement, with the result that its lower projection f4 presses the ink and paper rib-v bons upon the two type Wheels c2 and d2 as well as upon the block e and thereby causes an impression to be made such as that indi- -cated at w in Fig. 7. This impression thus consists of the numeral by which the cow giving the milk weighed is designated, an indicating arrow, and a portion of the scale with'one or more numerals thereof; the arrangement being such that the indicating arrow is opposite that portion of the scale corresponding to or indicating the exact weight of the milk. This second depression of the trigger k again feeds forward the ink and paper ribbons, after which the vbucket containing the milk may be removed and a second bucket holding milk from anothery cow may be suspended from the hook b;

The wheel d2 ma then be turned so as. to bring opposite t e arrow a7 4another numeral which shall be that by which the cow giving thisl second quantity of milk is designated, after which another depression of the trigger causes a third record to be made such as that indicated at m2. There is thus printed upon a relatively small and conveniently preserved lengt-h of ribbon, a record of the date, together with the weight of milk given by each cow of a herd, at the morning milking, and when it is desired to record the mllk given in the evening, the type wheel g* is turned so as to bring the symbol P. M. in line with the pointer, in place of that first used. The arm g is then moved to its Vertical position and a record made on the paper lribbon similar to that shown at m5, Fig. 7, except for the substitution of 1). M.

for .A. M.; it being noted that the parts are so arranged that no recordis made from the type wheels c2 and (Z2, when a record is taken from the date printing wheels.

1t is of course obvious that while our invention is particularly designed for weighing milk, it may, with equal advantage be employed to weigh and record the weight of any desired material. If desired, the front face of the wheel 02 may be provided with figures so that a visual indication may be had of the Weight of an object suspended from the hook 6.

By the use of the particular platen operating mechanism, described and illustrated, the force of the blow delivered by the platen for the purpose of printing a record is invariable, slnce owin to the action of the trigger it is altoget er independent of the operating force applied to said trigger. y

Vhile for thesake of brevity'we have referred to the parts b, b', etc., connecting the hook with the shaft or spindle c, as a balance, it will be understood that any other form of device may be substituted for these parts whereby there is caused a revolution of the said shaft proportional to the weight of the body hung to said hook.

While we have shown the preferred form of mechanism for operating the platen, it will be understood that any other operating means may be employed whereby the platen is caused to strike a. sharp blow so as to form a series of uniform impressions upon the record ribbon.

Although we have shown a series of independent dating Wheels carried on the arm 7', we may, if desired, modify the construction of this part of our invention or in some cases altogether omit it.
